The 'reconDesc' argument to rf_SignalQuiescenceLock() is a holdover from simulation code. *poof* Thanks to Simon B.

/* $NetBSD: rf_driver.h,v 1.8 2002/09/23 04:14:20 oster Exp $ */
RAIDframe, version 1.1, from the Parallel Data Laboratory at Carnegie Mellon University. Full RAID implementation, including levels 0, 1, 4, 5, 6, parity logging, and a few other goodies. Ported to NetBSD by Greg Oster.

Step 2 of the disentanglement. We now look to <dev/raidframe/*> for the stuff that used to live in rf_types.h, rf_raidframe.h, rf_layout.h, rf_netbsd.h, rf_raid.h, rf_decluster,h, and a few other places. Believe it or not, when this is all done, things will be cleaner. No functional changes to RAIDframe.

Get recent changes into the tree: - make component_label variables more consistent (==> clabel) - re-work incorrect component configuration code - re-work disk configuration code - cleanup initial configuration of raidPtr info - add auto-detection of components and RAID sets (Disabled, for now) - allow / on RAID sets (Disabled, for now) - rename "config_disk_queue" to "rf_ConfigureDiskQueue" and properly prototype in rf_diskqueue.h - protect some headers with #if _KERNEL (XXX this needs to be fixed properly) and cleanup header formatting. - expand the component labels (yes, they should be backward/forward compatible) - other bits and pieces (some function names are still bogus, and will get changed soon)

Nuke the 5 NULL parameters from rf_DoAccess(). Observe that 4 of the variables are passed directly to rf_AllocRaidAccDesc(), and the 5th isn't even used. Hunt them down and nuke them too.

Phase 2 of the RAIDframe cleanup. The source is now closer to KNF and is much easier to read. No functionality changes.
